The error message indicates you did not have the DISPLAY variable set. 
This is usally done when using an xterm but not in the cygwin console.

$ export DISPLAY=:0.0
$ gv

This seems like a problem with the threads which occured with personal firewalls
like ZoneAlarm or beacuse of /tmp being mounted in textmode

can you please try if

$ mount -buf $(cygpath -m /tmp) /tmp

If you're using ZoneAlarm5 you can downgrade to ZoneAlarm 4.5 which did not 
experience such problems.
